Officials conducted environmental testing after the Bridgeport Charter Township Offices were shut down due to a strange odor.

Several employees complained about the odor and reported feeling light-headed and nauseated on April 6.

The environmental assessment was done by AKT Peerless. On Tuesday, the township manager told TV5 preliminary testing found the presence of methane gas along the outside perimeter of the building.

On Wednesday, the company performed more testing to identify the source of the methane gas and to identify how the gas was entering the building. A timeline for these test results is not yet available.

Based on those findings, full-time operations at the building have been temporarily suspended and relocated to the water department, the township said. The Bridgeport Governmental staff are operating from the water department building.

Bridgeport Township is working with the Michigan Department of Environmental Quality to further evaluate the issue.

If you have any business to conduct with the township, you are being asked to call them at 989-777-0940.

The Bridgeport Township fire chief said they received about a half-dozen complaints over the past six months. The fire department has checked several times, but could not find anything, the chief said.
